WATER- sUPPLYrIXTURn AApplication filed Ncvemberl, 1924.r Serial No. 751,746.

'This invention relates to water supply connections for the separate hot and coldv water valvesfand the stopper are contained within a'single body or casing adapted to be set in an opening in the wall or slab of the basin or tub and having operating handles in juxtaposition at the outer end of the casingand the supply connections and flow controlling lvalves and connections to the stopper at the opposite end of` the casing;

The iixture `thus requires only one hole through the wall of the basin or tub, usually the horizontal wall at the edge of the basin or tub. The exposed parts of the xture mayv be made very-compact and of pleasing design, and it is especially convenientfor the use?. Beca-use of the single hole required, it is convenient and .relatively inexpensive to install. and the construction issuch that the costy ot' maintenance is also relativelylow'.

A full understanding of the invention can best be given by a detailed description of a fixture of approved form embodying all the features of the invention, and such a clescription will now be given in connection with the accompanying drawings which il? lustrate a basin fixture made in accordance with the invention. In said drawings:

Fig. 7 is afjplan view of the nonfrotatable washer between the handle disks;

. Fig. 8 is a detail view showingthe valve-A operating cams; and

Fig. 9 is a perspective view of one of the tension springs for the operating handles.

Referring to the drawings, the fixture has a hollow body, or main casing, '10 adapted to be setand secured in an opening in the' basin or tub wall 11 having at its upper or outer end a shoulder 12 to rest on the wall andbeing secured `by a ring nut 13 screwed on to the lower threadedfportion of the casing.l The casing is closed at its upper end except for acentral threaded opening'and a discharge spout 14 which extends from one side ofV the upper end of the casing. The

lower end of the casing is open and has secured toit an extension member 15 of hollow cyclindrical form `madeopen at both ends and vhaving on opposite sides inlet openings 16v through f short threaded bosses. The extension member is for convenience in assembling securedto the lcasing 10 by means of ya flanged collar 17 which 4is screwed on the upper end of the extension piece and is secured to the lower end ,of the casing 10 .by means of a flanged yring ynut 18 vscrewed on theslightly reduced end of the casing. The space within the casing and ex tension memberplis partitioned to provide a water space or chamber and an openended space Aextending from the upper end of the fixture to the lower end .of the extension member sealed from the water chamber. For this purpose in 'the construction shown, a tube 20,1nost desirably ,of thin copper,'is

provided having` an inwardly turned flange at its upper endiwhich isclamped against 'the upper end of the casing by means of a flanged bushing 21 which isscrewed upward into the threaded opening in the end of the casing, and having at its lower end an 0utwardly turned flange. which is clamped against the lower end of the extensionmemberv l5 by means'of a cap piece 22 `which is screwed on the lower end of thermember 15. The tube 2O thus forms a watertight partition between .the central space .within the tube and the surrounding water-space or chamber 23 vinto which the water passes from theinlet openings 16 and from which itfflows through the spout 14.

Two valves 25 and 26 for controlling the supply of hotv and cold water respectively are attached tothe Aextension member 15.

til!

Each or" these valves comprises a body casing 2T which is most desir-ably ot cylindrical torni and made open at both ends, and each has an inlet through an extension 28 from one side at its outer end tor connection to a supply pipe and an outlet through an eX- tension Q9 to which is screw connected a short flanged connecting pipe 30 which is secured by a ring nut 3l to the threaded boss about one of the inlet openings 16 oit the part l5. Through these connecti-ons the valves are supported from the extension member l5. rlhey are set in alignment with each other with their common airis intersecting at right angles the axis ot the main casing` l0 and tube 20. The inner ends of the valve casings are spaced apart and connected by a sleeve rlhe outer ends ot the valve casings are closed by caps 33 and the chamber within the casing of each valve is divided between the inlet and outlet by a partition disk which has a central port The flow of water through the port 35 is controlled by a valve head 36 which closes in the direction ot water flow and seats against a seat formed about the edge ot' he opening 35. rllflie valve head is pressed toward its seat by a spring 3'? and is carried by a stern 38 which extends through a central opening in a disk 40 screwed into the rear end of the valve casing. The passage of water out through the rear end of the valve casing is prevented by a corrugated cylindrical diaphragm, or bellows, al, ot' flexible metal which has at one end an inward flange which is clamped between a disk iange Ll2 on the valve rod and a flange on the end of a sleeve Llet which carries the valve head-and is screwed on to the threaded reduced end of the valve rod. The other end of the Abellows has an outward flange which is clamped against the plate l0 by a ring nut 45.

llhe valves are operated by means oi handles and 5l through concentric tubular spindles 52 and 53 which extend through the tube 2O and cams 5st and 55 on the lower ends ot the spindles. rlhe spindles 52 and 53 entend down through an upper opening 56 in the sleeve 32. The bushing 2l serves as a bearing for the upper end oi' the outer spindle 52, and the cap 22 provides a bearing for the lower end ot this spindle, and the spindleA provides a bearing for the inner spindle The reason tor' making the inner spindle tubular is to` accommodate a stop er-onerating rod as hereinafter eX- plained. The handles 50 and 5l when in normal closed, or ott position extend outward, desirably in opposite directions and in the same horizontal plane, from disks (Si) and (Sl. rlhe disk 6() is mounted on the upper end oi the spindle and secured by a set screw 62 (Fig. G). rlllie spindle 52 does not entend upward above tl e disk 60,

Lect/,507

and the disk 6l is mounted on the upwardly extending end ol" the spindle 53 and secured by a set screw 63.

rlhe handle disk seats on a disk Get which is screwed on the bushing 2l down against the top ot' the casing 10. Above the disk 64 the bushing is cut away except for two segmental portions 65 which e-:tend up through the handle disks. The handle disks are formed with segmental cut outs to receive the upa-'ard extensions ot the bushing, the cut outs (S6 of the disk 50 being so located and of such length as to permit the handle to be turned 'forward from its normal position `the desired amount, that is, in the liXtu-ie shown, through about 45o, and the cut outs 67 ot the diskl being so located and ot such length that the handle lmay be turned forward a similar distance from its normal position. A disk 70 rests on the top ot the Lipper handle disk 6l, and a cap nut 7l screwed on to the ends oit the upward extensions 65 ot the bushing 2l holds the disk [0 in place. To prevent the turning movement of one handle disk causing a turning oi the other handle disk, a nonturnable washer 72 is provided between the two handle disks, this washer being held against turning by having its central opening formed with inward projections to eX- tend between the segmental extension v65 ot the bushing 2l as shown by F ig. 7.

n order to avoid lost motion between the handle disks and the disks 64: and 70, and on the other hand, to avoid having the handle disks held too tightly between the disks :6d and 70, while securing a desirable snug lit and easy resistance to movement ot the han-V dles, spring rings 7 3 are provided, one set in a channel in the upper face of the disk Gel to bear against the under 'face of the liandle disk Gl, and the other set in a channel in the under face of the disk 70 to bear against the upper face of the handle disk 6l. 'lhese spring rings may be ot' spring wire of a diameter less than the depth ot' the channels and bent in an axial direction to bear against the bottom ot the channel and thetace ot the handle disk at spaced points,

The cam 54 is made hollow on its under side to accommodate the cam 55 as shown in Fig. l. Vihen the operating handles 50 and 5l are in their normal or off position, low points of the cams 5st and 55 are opposite the respective valve rods 38, and the cams are shaped so that when either operating handle is moved forward the corresponding cani will push its cooperating valve rod outward 'to 'torcethe valve head 36 away from its seat against the pressure of its spring 37. When the operating handle is moved back to normal position the cam permits the valve head to be closed against its seat under the action of its ,springf` The: inclination'of the operating faces of the camsy is desirably such that the turn the spindle and handles back to normal position when1 released' after being turnedto open, or on, position.

As is usually desirable,`and`as shown, the ixture vis provided with stopper-operating means. For this purpose, the spindle 53 is made tubular and a stopper-operating rod 80' is provided which extendsthrough the spindle 'andv iinds its bearingtherein. rhe upper end of the rod 80 extends through anopening in the cap' nut 71 and has'fastened toit an operating knob 81.' The lower end of the ro'd projects'through an opening in the lower side of the sleeve 32 and is adapted to operate a stopper'through suitable connections. yIn the example shown, the 'end df the r'od is threaded and-has screwed thereon aconnecting yokev 82 which is pivo'tally connected to a link 83 the lower end offwhich is pivoted to a. short arm 84 ona rock' rod 85 extending from a basin outlet litting 86 which 'may be of any' suitable construction such that the'turni'ng'fv of the rod 85 raises vor'lowers the basin' stopper 87. Thethreaded connection between. the yoke 82 and the lower .endv of the operating rod 80 provi'des'for ain adjustment longitudinally of the rod, and ar lock nut is provided for setting the ports when adjusted. The arm 84 is Vlongitudinally adjustable on the rod 85. Provision is thus made for adjustment of the stopper-operating connec tions in two directions at right angles to each other. f n

It will be seen that the construction of the fixture is Ysuch that it may be readily, in-

'l stalled in position or removed or taken apart for access to its dierent parts. For in. stallation it is necessary only thatjthe valves 25 and 26 be disconnected from the "assemf bled main portion of the lixture'by'unscrewing the ring nuts 31. Thefassembled main casing and 'extension' member 15 with the other parts carried thereby, and the ring nut 13 being removed, then have no parts projecting beyond the dimensions oi' the main body portionof the main casing below its upper shoulderl 12, so that this part of the fixture may be' placed in position in the opening in the basin or tube wall from above. The ring nut 13 is then screwed up on the threaded portion of the casingagaiiist the bottom wall. l'The valves, connected by the sleeve 32, are then positioned with relation to the* extension member 15 and secured by the flanged ring nuts 81, 'and connection isA made betweenV the lower Iend ot thestopper rod^ and thestopper-operating-mechanism and the hot water supply pipes are `connected -to the valve casings. If access to either off the-'valves becomesnecessary, the valvesrarey readily removable by simply unscrewing Vthe yring nuts 3l and dropping the valves away from the body portion of the fitting, and disconnecting the yoke 82 from theY rod 80. The sleeve 32 by which the inner ends of the valve casings are connected desirably has a threaded Vconnection 'with one of theA valve casings and a slip-on connection with'the other, or the arrangement may-be otherwise such that vthe valves when removed from t-he body of the fitting may bereadily separated.` lThe sleeve 32 Vis desirably A of such length as to extendv the valvecasings a sufficient distanceto-holdy the 'casingsesub stantially rigidlytogether and preventrelative movement 'of the casings, thus preventing'anyl turning strain on the' connections between the valvecasings and theextension member 15. Ifdesired, either valve may be removed without disconnecting the v'other valve Afrom the member 15. The interior of either valve is also readily accessible without moving they valves from lthe main body of the iixture by ysimply unscrewing the cap 33,*'and if it is desired to goffurther,` un-` screwing the sleeve 44 and the partition diskV 34;

' The use in the claims of the terms upper7 and lower and other terms Vreferring 'to the lixture or parts thereofas though the fix-A ture wereset, as it usually'is, with its principal axis vertical, is for convenience and is not to betakeii 'as limiting the invention to a fixture set vertically.
